Small set of field lines for each of our four models of three-dimensional, X-shape + spiral magnetic fields in galactic halos, as seen from an oblique angle. The parameters of the poloidal field take on the same values as in Fig. 1, while the pitch angle is assigned a constant value of p =  −30°, plausibly representative of galactic halos. The selected field lines correspond to those displayed in Fig. 1 (i.e., they have the same labels (z₁,ϕ₁) or (r₁,ϕ₁)), except in model D, where only four field lines are drawn for clarity. Each box is a (30  kpc)³ cube centered on the galactic center. The trace of the galactic plane is indicated by the solid red circle, and the z-axis by the vertical, dot-dashed black line.
